The present study sought to clarify the neural bases of social behavior in Octodon degus, a social rodent. For the good communication, it is important to discriminate or identify conspecifics, and to modify behavior depending on the serial behavior of others. We clarified that the degu hippocampus plays a important role in social recognition as well as spatial recognition. Our findings suggest that complex and higher cognitive processing requires the functioning of the hippocampus in degus.
